Best To Sleep On It: Brain Activity Patterns During Sleep Consolidate Memory
Science Related News
Why does sleeping on it help? This is the question tackled by new research, which reveals how brain activity during sleep sorts through the huge number of experiences we encounter every day, filing only the important information in memory.
Sleep duration varies by alcohol drinking patterns, race, and sex
Compared to their white counterparts within each alcohol drinking pattern (Never, moderate, excessive) investigated, black men and women were significantly more likely to get less than six hours of sleep, less likely to get seven to eight hours of sleep and generally more likely to get nine or more hours of sleep. Short sleep disparity increased with increasing alcohol consumption between black and white men. Long sleep duration was more common among heavy drinkers, but only in black men and white women. Ref.

Possible missing link between sleep and improved memory
A team of sleep researchers has found that the autonomic nervous system, which is responsible for control of bodily functions not consciously directed (Such as breathing, heartbeat, and digestive processes) plays a role in promoting memory consolidation -- the process of converting information from short-term to long-term memory -- during sleep.

Plenty of light during daytime reduces the effect of blue light screens on night sleep
The use of smartphones and tablet computers during evening hours has previously been associated with sleep disturbances in humans. A new study now shows that daytime light exposure may be a promising means to combat sleep disturbances associated with evening use of electronic devices. Ref. Source 7a.
I don't feel that sleep can be made up. Three hours of sleep one night followed by 13 the next doesn't equal two nights of eight hours sleep. There is definitely a difference between deep sleep and light. Those nights I get eight plus hours I usually dream and wake up feeling great. The nights with three or four hours sleep I feel miserable and don't dream. I try not to let it affect me but I have to get at least seven hours sleep a night to function as my usual sweet self and not as angry me.
I know that if I do not get at least 5 hours of sleep the next day I am not very productive but I still get a lot done. I think society today has made getting eight hours of good sleep hard to get. Sometimes pushing seven hours is difficult too.
When I was doing physical training I was ok with 4-6 hours of sleep. Now that I am making mostly mental work I cannot sleep less than 8 hours. In my region/country the afternoon sleep is a tradition and it works to break the sleep into 6-7hrs and 2-1hr.
However I am sleeping more than 10hrs a day now because the mental work drains me a lot.
